and useful Improvements in Rotary Cutlasses, of which the following is a specification.

' The purpose of the invention is to provide an apparatus'for use in warfare, the apparatus being particularly designed for mounting upon an auto vehicle or auto truck and comprising a plurality of rotatably mounted blades or cut-lasses, which will stand out beyond'the forward end of the vehicle or truck on which they are carried, thus providing a simple but effective device foruse in warfare.

As shown and described, a specific embodiment of the invention is adhered to, but to this embodiment the invention is not to be restricted. ."Theright is reserved to make such changes or alterations. as the actual reduction topractice may suggest, in so far as such changes or alterations, are compatible in spirit with the annexed claim. 7 The same numerals of'reference' designate the same parts throughout the several figures of the drawings, wherein:

Figure 1 is a view in side elevation showing the improved apparatus mounted adjacent the forward end of an auto vehicle.

7 Fig. 2 is a top plan view of the structure of Fig. 1. W

Fig. 3 is a rear elevational view of the frame supporting the mechanism of the device.

Fig. is a perspective View of a section of the batteryof rotary knives or cutlasses.

'Referring to the drawings, the invention is shown mounted on an auto vehicle 1, and comprises a frame'consisting of the rail 2 which is disposed transversely with reference to the vehicle, this rail being provided with the upstanding bearing sup-ports 3 arranged in pairs, each pair carrying the stationary shaft 4 near their upper ends. The rail 2 extends laterally from both sides of the vehicle to provide means for the attachment of brace members hereinafter described. Mounted upon theshafts, 4' there are bearing members 6 which are'movable longitudinally along the shafts and these bearing members have pivotally connected to them the arms'ifithe arms connecting with the 'bearing niembets at-one end and at the of the latter.

other endpivotally connecting with a collar 7 member 8 on diametrically opposite sides The collar member 8 is car ried by one end of a tubular member 9 which is formed at one end with the forked mem her 10, the latter near. the extremities of its legsbeing formed with appropriate bearings for the support of thetransversely disposed shaft 11', the latter carrying the knivesor cut1asses12 disposed on diametrically opposite sides of the shaft, and at uniformly spaced intervals therealong. At the ends of the shaft 11 there are carried the cutting disks 13."

The tubular member 9 is suitably braced between the collar member 8 and its forked member 10, and to this end there are provided the lattice work brace members 14;. These brace members 14 at one end pivotally connect with'the tubular member and at the other ends with the extremities of the sill 2 by means of staples as indicated at 15. y

The tubular member 9 is adapted to swing from a position substantially in a horizontal plane to a position at an acute angle to the horizontal plane. Thus the shaft 11 is raised and lowered with the resultant raising and lowering of the cutlasses 1'2 and disks .13 when the device is in operation. To effect this there is mounted on the sill 2 atan intermediate point a support 16 on ,1

top of whichthere is carried a toothed sec- .tor 1 7, the latter having pivotally mounted thereon a hand lever 18 having a spring latch 19 which engages between the teeth of, the sector.' This lever 18 connects with the brace members 14, connecting rods 20 being provided for the purpose and pivotally attached to the lever 18 at one end, the opposite ends being pivotally connected with the brace members 14, as indicated at 21.

A pair of pivotally connected links 22 have their extremities pivotally connected with the arms 7 and as the arms are moved to increase or decrease their spread, the angle of these links is increased or diminished.

The purpose of this arrangement. appears hereinafter.

As a means for rotating the shaft 11,'the

vlatter carries a bevel gear 23 mounted on it from the'under face of the sill 2. The shaft 29 has a thrust bearing in the end of a laterally projecting arm 31 carried by a support 32 attached to the under face of the sill 2,

and this support 32 carries an arm 33 which provides a bearing for the shaft 29' at an intermediate point.

The support32 carries a horizontally disposed shaft 34: and the latter is designed to be set in motion by a ulley 35 to which a belt (not shown) is led from some driving 'means (not shown). VOb'viously, a gear or a sprocket wheel. may be used in place of the pulley 35 to secure rotation of the shaft 34.-

A bevel gear couple consisting of the driven construction being made shorter.

gear 36 and the driver 37 operatively connect the shafts 34 and 29,

It is apparent that motion transmitted to the shaft 34 will effect rotation of the shaft 11 with the'consequent rotation of the knives or cutlasses l2tand thecutting disks 13 and rotation imparted to these members will serve to convert the device into an effective mechanism for offensive operation in warfare. 1

The hand lever 18 previously referred to serves as a means for elevating and lowering the shaft 11 so that the positions of the cutlasses 12 and disks 13 may be changed with reference to the ground. Swinging the lever 18 backwardly will effect the raising of the forward end of the tubular member 9 with the consequent raising of the shaft 11,

will spread apart, the bearing members 6 sliding along their attendant shafts toward the outboard bearing members 3 and the shaft 27 as a consequence of its telesco ic he ,journaled in a bracket 30-which depends throwing forward of the lever18 effects the reversing of this operation, the bearing members 6 moving-in. the oppositedirections along their shafts to move the arms 7 toward each other and sectional shaft 27 lengthenout.

in c

Ihe pivotally connected links 22 serve to secure the. two arms 7 each in the same position with'respect to its attendant arm.
